I will explain how to find the dot product in Python.

If you're not familiar with Python in the first place, read an article that explains what Python is and get a better understanding.

This article is based on the contents of the TechAcademy online boot camp Python course.

## What is the dot product?

It is one of the vector operations and is also called the inner product.

It is used in various vector calculations in mathematics and physics.

## How to find the dot product (how to use numpy.dot)

To calculate the dot product in Python, use the dot function of the numpy module.

The dot function takes two arguments.

If the argument is a one-dimensional vector (array), the inner product of the two vectors is calculated.

If the argument is a 2D vector (matrix), the matrix multiplication is calculated.

See the official documentation for details.
